You will love the power jack vs your manual. Its a great addition.
The Ultra Fab Odyssey is a good jack from owner reviews that I have read. Some have had to replace after a couple of years while most seem happy. There really aren't any secrets to building an electric jack but I stay away from the really cheap no-name brands. Those often strip their gears. Good brands are Barker, Atwood, Ultra Fab. I really like my Barker that I upgraded to when replacing the stock LCI (Not no-name but known to fail prematurely).
You can buy the Odyssey for much less $$ than at CW right now. I've seen it for $125 If you want to install yourself. Its a simple process.
Other thoughts: It's head looks pretty big so make sure it fits. It has 18" of travel - Some people want longer but those can be tall.
